Savanna - Failed to create database

Hi,

I have OpenStack Grizzly set up with a controller node and two compute nodes. All systems run Ubuntu 12.04 64-bit.

I followed the following guide : https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst#4-compute-node

Now i am trying to integrate Savanna 0.3 into my setup and i used the following installation guide : https://savanna.readthedocs.org/en/latest/userdoc/installation.guide.html

I have set up savanna in a virtual environment.

Now when i try and run savanna by using the command, it fails to create a database. $ savanna-venv/bin/python savanna-venv/bin/savanna-api --config-file savanna-venv/etc/savanna.conf

The following are excerpts from the log.

2014-02-24 17:32:35.697 18858 ERROR savanna.db.sqlalchemy.api [-] Database registration exception: (OperationalError) unable to open database file None None .... 2014-02-24 17:32:35.708 18858 CRITICAL savanna [-] Failed to create database! .... 2014-02-24 17:32:35.708 18858 TRACE savanna raise RuntimeError('Failed to create database!') 2014-02-24 17:32:35.708 18858 TRACE savanna RuntimeError: Failed to create database!

Here is my savanna.conf configuration file :

[DEFAULT]

Hostname or IP address that will be used to listen on

(string value)

host=

os_auth_host=10.204.142.58 os_auth_port=35357 os_admin_username=admin os_admin_password=password os_admin_tenant_name=service

If set to True, Savanna will use floating IPs to communicate

with instances. To make sure that all instances have

floating IPs assigned in Nova Network set

"auto_assign_floating_ip=True" in nova.conf.If Neutron is

used for networking, make sure that all Node Groups have

"floating_ip_pool" parameter defined. (boolean value)

use_floating_ips=false

Use Neutron or Nova Network (boolean value)

use_neutron=true

Postfix for storing jobs in hdfs. Will be added to

/user/hadoop/ (string value)

job_workflow_postfix=

Enables Savanna to use Keystone API v3. If that flag is

disabled, per-job clusters will not be terminated

automatically. (boolean value)

use_identity_api_v3=true

enable periodic tasks (boolean value)

periodic_enable=true

Enables data locality for hadoop cluster.

Also enables data locality for Swift used by hadoop.

If enabled, 'compute_topology' and 'swift_topology'

configuration parameters should point to OpenStack and Swift

topology correspondingly. (boolean value)

enable_data_locality=false

Print debugging output (set logging level to DEBUG instead

debug=true

Print more verbose output (set logging level to INFO instead

of default WARNING level). (boolean value)

log_dir=/var/log/savanna/

Use syslog for logging. (boolean value)

use_syslog=true

syslog facility to receive log lines (string value)

Can someone please guide me on this? Thanks a lot.
